Re: Ebike Ideas for the Masses?

We have basic commuter ebikes, good for most terrain and loads and for under 8 miles one way, recharge at work. Then the advanced ebike, good for quite a bit more in range, power, load carrying, and speed. And we have ebike systems capable of 95%+ car replacement, for the "Car light" and the "car v...

Re: Advice on Cyclone kits

I have both cyclone and hub motor ebikes. Cyclone and most mid drives are (argueably) better at being able to stay on the sweet spot of the motors efficiency and power curves. This is important if you have a demanding load due to rider, terrain or cargo. If you are a big guy with a large frontal are...

Re: Ebike Ideas for the Masses?

Me thinks that although other frame designs are more efficient, a DF, or close to a DF is what would be acceptable to the masses. After all, if 'bents or semi bents, (which I own and love and are my favorites) were beloved by the masses, then they would be selling more as straight human powered. The...

Re: NiMH battery packs for regen?

Yes my Bionx 36v NIMH sytems have regen. Its value is more as an outstanding brake than the amount of energy returned to the battery.

In some "overvolted' systems, the higher charge voltage might get real close to the maximum allowed voltage for some of the controller components, so disconnect those.

Re: How long before charging?

I've read that after using your batts you should charge them up right away to keep them lasting longer. But I can't charge up at work. How bad is it to ride to work and let them sit for about 9 hours and then ride home before charging? When I first got the ezip it would go 18 mph on its own power. ...

Re: Multiple Cyclone Motors

another thing you might consider is running your cylone 360 at 30 volts. that might be enough power for youe. Just put a 6v SLA in series with what you have and test out the power and speed. I that will suffice, we can figure out how to do it correctly and charge it. Are you running out of power to ...

Re: reducer stops

Just to see if something else is a problem, can you come up with a small 12v battery and use it for a short attempt?

If this fails the same way, then its not a reducer. Yeah with a fuse.
